The Impact of the Thermal Seasons on Adenoid Size, Its Mucus Coverage and Otitis Media with Effusion: A Cohort Study

Background: The purpose of this study is to analyze seasonal differences in adenoid size and related mucus levels via endoscopy, as well as to estimate changes in middle ear effusion via tympanometry. Methods: In 205 children with adenoid hypertrophy, endoscopic choanal assessment, adenoid hypertrophy assessment using the Bolesławska scale, and mucus coverage assessment using the MASNA scale were performed in two different thermal seasons, summer and winter. The study was conducted in two sequences of examination, summer to winter and winter to summer, constituting two separate groups. Additionally, in order to measure changes in middle ear effusion, tympanometry was performed. Results: Overall, 99 (48.29%) girls and 106 (51.71%) boys, age 2–12 (4.46 ± 1.56) were included in the study. The first group, examined in summer (S/W group), included 100 (48.78%) children, while the group first examined in winter (W/S group) contained 105 (51.22%) children. No significant relationship was observed between the respective degrees of adenoid hypertrophy as measures by the Bolesławska scale between the S/W and W/S groups in winter (p = 0.817) and in summer (p = 0.432). The degrees of mucus coverage of the adenoids using the MASNA scale and tympanograms were also comparable in summer (p = 0.382 and p = 0.757, respectively) and in winter (p = 0.315 and p = 0.252, respectively) between the S/W and W/S groups. In the total sample, analyses of the degrees of adenoid hypertrophy using the Bolesławska three-step scale for seasonality showed that patients analysed in the summer do not differ significantly when compared to patients analysed in the winter (4.39%/57.56%/38.05% vs. 4.88%/54.63%/40.49%, respectively; p = 0.565). In contrast, the amount of mucus on the adenoids increased in winter on the MASNA scale (p = 0.000759). In addition, the results of tympanometry showed deterioration of middle ear function in the winter (p = 0.0000149). Conclusions: The obtained results indicate that the thermal seasons did not influence the size of the pharyngeal tonsils. The increase and change in mucus coverage of the adenoids and deterioration of middle ear tympanometry in winter may be the cause of seasonal clinical deterioration in children, rather than tonsillar hypertrophy. The MASNA scale was found to be useful for comparing endoscopy results.

Evaluation of Caspase-1, Interleukin-1β, and Interleukin-18, in the Middle Ear Effusion in Children With Otitis Media With Effusion

Objectives: The present study aimed to assess the expression of caspase-1 and caspase-1-dependent processing of cytokines, such as interleukin (IL)-1β and IL-18, in the middle ear effusion of children with otitis media with effusion (OME) in order to identify the potential role of inflammasomes in OME.Methods: This study included 29 children scheduled for myringotomy with the insertion of tympanostomy tubes due to OME. Middle ear effusion (MEE) was collected during the surgery. Caspase-1, IL-1β, and IL-18 were assayed using enzyme-linked immunosorbent assay kits. The levels were compared between those with mucoid and serous MEE and those with and without a history of ventilation tube insertion.Results: Caspase-1, IL-1β, and IL-18 were detected in all samples. The caspase-1, IL-1β, and IL-18 levels did not significantly differ between mucoid samples and serous samples. No statistical significances were discovered in caspase-1, IL-1β, and IL-18 levels between with and without a history of ventilation tube groups. There was a significant negative correlation between IL-1β and IL-18 and the duration of OME (p < 0.05). However, no significant correlation was found between caspase-1 and disease duration.Conclusions: Inflammasomes may participate in the inflammatory process of OME. IL-1β and IL-18 levels in the MEE decreased over time.

Effect of Erdosteine on Middle Ear Effusion in Rats by Mediating TLR4 Signaling Pathway

The study aimed to investigate the effect of erdosteine on middle ear effusion in rats through mediating the Toll-like receptor 4 (TLR4) signaling pathway. Rats were injected with endotoxin to prepare the model of acute secretory otitis media (SOM). Then, they were divided into an acute SOM model group (model group, n = 15 ) and erdosteine treatment group (18 mg/kg, gavage, treatment group, n = 15 ). Besides, a normal group ( n = 15 ) was set up. Two weeks later, routine biochemical indicators such as aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were detected. The inflammatory effusion due to otitis media was scored. The content of myeloperoxidase (MPO), matrix metalloproteinase (MMP), and tumor necrosis factor-beta (TNF-β) in middle ear lavage fluid was detected via enzyme-linked immunosorbent assay (ELISA). Additionally, histomorphological changes were observed with the help of hematoxylin-eosin (HE) staining, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting assays were carried out to measure the expression levels of TLR4 pathway genes and proteins as well as the messenger ribonucleic acid (mRNA) expression levels of key factors for otitis media (mucin 2 (MUC2) and MUC5A). In the model group, the levels of AST, ALP, and glutamic-pyruvic transaminase (GPT) were significantly increased ( p < 0.05 ). Besides, the content of MPO, MMP, and TNF-β was overtly raised in the model group ( p < 0.05 ), while it was notably lowered in the treatment group ( p < 0.05 ). In the treatment group, the cilia were slightly swollen, and inflammatory cells were fewer. The mRNA levels of MUC2, MUC5A, and pathway genes TLR4 and c-Jun N-terminal kinase (JNK) were elevated in the model group. In addition, the protein assay results revealed that the protein levels of TLR4 and JNK were evidently increased in the model group. Erdosteine can treat the middle ear effusion in rats by repressing the activation of the TLR4 signaling pathway.

The effect of intervelar veloplasty under magnification (Sommerlad’s Technique) without tympanostomy on middle ear effusion in cleft palate patients

Objective Different surgical techniques and management approaches have been introduced to manage the cleft palate (CP) and its complications, such as otitis media with effusion (OME) and auditory problems. The optimal method, as well as the ideal time for palatoplasty and ventilation tube insertion, are the subject of controversy in the literature. We aimed to evaluate The Effect of Intervelar Veloplasty under Magnification (Sommerlad’s Technique) without Tympanostomy on Middle Ear Effusion in Cleft Palate Patients. Methods non-syndromic cleft palate patients from birth to 24 months who needed primary palatoplasty from April 2017 to 2019 were enrolled in this study. intravelar veloplasty (IVVP) surgery under magnification has been done by the same surgeon. Likewise, Otoscopy, Auditory Brainstem Response (ABR), and tympanometry were performed for all the patients before and six months after palatoplasty. Results Tympanograms were classified into two categories according to shape and middle ear pressure, and it was done in 42 children (84 ears). Type B curve was seen in 40 cases (80 ears) before surgery which reduced significantly (P < 0.005) to 12 cases in the left ear and 14 cases in the right ear after surgery. So, after surgery, 70 % of the tympanogram of left ears and 66.6 % of the tympanogram of Rt ears were in normal condition (type A tympanometry). ABR was done for 43 patients (86 ears) before surgery and six months after palatoplasty. Data were shown that 40 of the patients had mild to moderate hearing loss before surgery, which reduced significantly (P < 0.005) to 9 in the left ear and 11 in the right ear after palatoplasty. So, after surgery, 79 % of ABR of left ears and 73.8 % of ABR of right ears were in normal status (normal hearing threshold). Conclusions Intervelar veloplasty under magnification (Sommerlad’s technique) significantly improved the middle ear effusion without the need for tympanostomy tube insertion.

Conductive Hearing Loss: A Case Report

In this case report, osteopathic manipulative treatment restored hearing to an 8-year-old female suffering from conductive hearing loss. Numerous factors can result in hearing loss. In children and adolescents, mild or greater hearing loss occurs with a prevalence of 3.1%.1 Current osteopathic literature focuses on conductive hearing loss due to middle ear effusion (MEE).This case report examines an 8-year-old female presumed to have permanent conductive hearing loss without MEE after a traumatic ATV accident. The use of osteopathic manipulative treatment (OMT) resulted in complete resolution of the patient’s conductive hearing loss. To the authors’ knowledge, this is the first case report documenting the successful use of OMT to treat conductive hearing loss without MEE. Being able to recognize and understand the connection between the primary respiratory mechanism (PRM), which includes the cranial bones and nerves, allows an osteopathic physician to provide a unique approach to patient care and the use of OMT as a treatment modality for conductive hearing loss should be considered.

Postoperative results of ventilation tube insertion: a retrospective multicenter study for suggestion of grading system of otitis media with effusion

Background In otitis media with effusion (OME), it is important to know when to surgically intervene and when careful monitoring is more appropriate. This study aimed to visualize and classify the clinical manifestations of OME and the correlation between the new grading system and postoperative results after ventilation tube insertion (VTI). Methods We classified the collective 1,012 ears from 506 patients into six groups: grade 0 (no effusion), grade I (scant effusion, but abnormal), grade II (effusion less than half of the tympanic cavity), grade III (effusion over half of the tympanic cavity, with air bubbles), grade IV (complete effusion), and grade V (retracted tympanic membrane or hemotympanum without air bubbles). Results The mean age at VTI was 5.2 (±2.9) years and mean duration between diagnosis and operation was 4.1 (±1.8) months. Between the grades, the nature of the middle ear effusion was also significantly different (p < 0.001). The duration of ventilation tube retention after VTI was significantly different when compared between two groups: grade I-IV and grade V (p = 0.019). Our results showed that the recurrence rate, as well as rate of revision VTI, increased as the grade increased (p < 0.001). Conclusions The new grading system of OME using endoscopic otoscope evaluation had a significant correlation with the age at VTI, the nature of middle ear effusion, the recurrence rate of OME, and the rate of revision VTI.
